Thousands gather for annual AIDS walk

As many as 25,000 people are expected to gather in Golden Gate Park this morning to take part in the city's 25th annual AIDS Walk San Francisco.

Since the first AIDS Walk in 1987, more than $74 million has been raised for Bay Area HIV/AIDS service organizations, according to official totals released by organizers.

Total donations collected by this year's volunteers, sponsors and participants will be announced at about 2:30 p.m. at a post-walk celebration at Sharon Meadow, where the 6.2-mile walk begins and ends. More than $3 million was raised at the event in 2010.
